Abstract

Roket memiliki gerak enam derajat kebebasan yang meliputi tiga kebebasan gerak translasi dan tiga kebebasan gerak rotasi pada tiap sumbu koordinat kartesian. Roket dapat dikendalikan dan dipandu untuk bergerak dalam lintasan yang telah dikalkulasikan untuk mencapai target yang telah ditentukan. Karena roket bergerak bebas di ruang udara, gerak roket mengalami berbagai macam nilai input gangguan berupa noise, salah satu diantaranya adalah gangguan angin. Fenomena angin yang terjadi di udara dapat terjadi secara konstan maupun secara acak. Hal ini menjadi permasalahan sistem pemandu untuk memberikan panduan gerak kepada roket supaya mencapai target. Estimasi state roll, pitch, dan yaw menggunakan Extended Kalman Filter (EKF), memperbaiki perhitungan pemanduan gerak roket yang menjadi masukan kalkulasi sinyal kontrol. Hasil simulasi diuji dengan pembuktian simulasi Monte Carlo dan uji akurasi sistem pemanduan yang menunjukkan perbaikan kinerja sistem pemanduan dengan mengimplementasikan EKF mendekati perilaku riil.

In Cartesian coordinate, rocket motion has six degree of freedom (dof) consisting of three dof of translational motion and three dof of rotational motion (attitude). During its flight, a rocket might be disturbed, e.g., by the wind in form of stochastic turbulence. This turbulence induces inaccurate information of the states of the rocket supplied to the guidance system. In this final project, an Extended Kalman filter is designed to estimate the attitude of the rocket to improve the performance of the guidance system. The effectiveness of the design is evaluated by a Monte Carlo simulation. It is shown that the filter can improve the performance of the guidance system by supplying better estimates of the rocket attitude.
